Observations — The \ iscid pileus, its deep blood red color, and the 

 somewhat Hbrillose striate margin are the important diagnostic charac- 

 ters of the species. We have not been able to verify the differences 

 between H. COCcinetlS and //. puniceus as pointed out by Kaullman. 

 For a critical comparison of these two see //. coccineus (page L8 

 The spori 1 size varies considerably In specimens with 4-spored basidia. 

 This added to the fact that 2-spored forms are also known to occur 

 (also 1- and 3-spored), makes spore size a rather poor character to use 

 in distinguishing this species from its close relatives.

 Bresadola, Icon. Myc, pi. 343. 



Pileus 3-6 cm broad, convex with an incurved margin, expanding 

 to plane or the margin uplifted and somewhat crenate, blood red to 

 scarlet when young but soon fading to orange-red and finally to 

 yellow (orange-yellow to yellow dried), glabrous, viscid but soon dry. 

 Context yellowish; odor and taste not distinctive. 



Lamellae adnate to adnexed, orange-vellow to pale yellow, 

 moderately broad, subdistant, edges even. 



Stipe 4-6 cm long, 3-6 mm thick, concolorous with pileus. equal or 

 nearly so, often becoming compressed, glabrous and naked, moist. 



Spores 7-10 X 3.5-5 /x, narrowly ellipsoid, at times faintly con- 

 stricted, smooth, pale yellow 7 in Melzer's reagent. Basidia 34-41 X 5-7 p, 

 2- and 4-spored. Pleurocystidia and cheiloc) stidia not seen. Gill trama 

 parallel or nearly so, hyphae 7-14 fx broad. Cuticle a thin gelatinous 

 pellicle of narrow hvphae (an ixocutis). No hypodermium differen- 

 tiated. Pileus trama of radial hyphae. Clamp connections present on 

 the hyphae of the cuticle, gill trama, and subhymenium.
